Informe actividad solar
Any mentioned solar flare in this report has a scaling factor applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor, solar flares are reported as 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.

Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 237 Publicado el 2200Z a las 25 AUG 1999IA. Análisis de regiones solares activas y de actividad desde 24-2100Z hasta 25-2100Z SOLAR ACTIVITY WAS MODERATE. REGION 8674 (S24E11)
PRODUCED AN M3/1N EVENT AT 25/0136Z WITH AN ASSOCIATED TYPE II SWEEP
AND A 310 SFU 10CM RADIO BURST. THE TYPE II HAD AN ESTIMATED SPEED
OF 500 KM/S. REGION 8674 ALSO PRODUCED A C6/SF AT 25/1504Z.
SEVERAL OTHER OPTICALLY UNCORRELATED MINOR C-CLASS EVENTS OCCURRED
DURING THE PERIOD. REGION 8676 (N26E61) DISPLAYED SLIGHT GROWTH
SINCE YESTERDAY. NEW REGIONS 8677 (N07E71) AND REGION 8678 (N16W40)
WERE NUMBERED TODAY.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE. REGION 8674 IS STILL THE MOST LIKELY TO PRODUCE AN
M-CLASS EVENT.
IIA. Resumen de la actividad geofísica 24-2100Z a 25-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED WITH THE POSSIBILITY OF ISOLATED
ACTIVE PERIODS.
